Three Uruguayan soldiers died on a night training swim, and the Army’s own report on what went wrong is now in the hands of a prosecutor.

Uruguay’s Army report on the deaths of three soldiers in a diving course reached the prosecutor in Fray Bentos on Friday, 6 November 2026. Prosecutor Guillermina Chouhy received the document through the Prosecutor General’s office, which had it from the Defence Ministry.

The three men died during a night swim on the Uruguay River. The report is meant to show how the exercise was planned and authorised and how the emergency was handled.

What Happened on the River

The deaths occurred in a night exercise at the end of October 2026, during the Army’s Tactical Divers Course No. 64, a training course for soldiers who specialise in diving. It was a night swim on the Uruguay River off Fray Bentos, in the Río Negro department.

Army chief General Mario Stevenazzi has said that the group was tied to one rope and that some soldiers stayed under water. The cause is still to be determined.

One soldier was pulled out alive. The other three were lost in the river and later found dead.

Tactical divers are soldiers trained for swimming, diving and operations in water. In this exercise the group was tied to one rope, which was cut when some men became entangled.

A “fiscal” in Uruguay is a public prosecutor. Fiscales lead criminal investigations.

Two Investigations, One Set of Questions

The Army opened an internal “urgent” administrative inquiry right after the deaths. Its aim was to establish how the exercise was planned and authorised, what safety conditions were foreseen and how the emergency response unfolded.

Stevenazzi received the finished report, which is to go to Defence Minister Sandra Lazo so she can weigh whether any responsibilities require action. The same document reached the prosecutor through the ministry, and the criminal inquiry runs separately from the Army’s own review.

Chouhy, the Fray Bentos prosecutor, will analyse the document in the coming days while the investigation continues. The prosecutor’s investigation of the deaths continues.

A Country in Mourning

The government declared official national mourning for 3 and 4 November, with flags at half-mast on all public buildings, barracks, air bases and warships. The decree was signed by President Yamandú Orsi and Minister Lazo.

The Río Negro departmental government also declared local mourning. Second Lieutenant Braian Ruiz, the only survivor, has left intensive care and is on an ordinary ward of the Military Hospital in Montevideo.

What It Means for You

For readers who follow Uruguay as a stable base for living or investing, the case shows two processes running in parallel. The military and the prosecutors are examining the same events through separate channels.

Families of the dead and the public will look for two things in the coming weeks. One is whether the report finds failures in planning or safety, and the other is whether the prosecutor sees grounds for criminal responsibility.

What Is Not Known

The contents of the Army report are not public, and the cause of the sinking has not been established. It is not known when the prosecutor will decide whether anyone is to be charged.
